Definitions

  • This invention relates to a bed having a base, a mattress, and a system for moving the mattress up and down to help a person to make the bed, which can be preferably adapted in a guest room of hotels or the like.
  • Making the bed is one of the routine jobs for a person in charge of fixing the guest rooms in the hotels, in which the person spreads bed-clothes such as sheets and blankets over the mattress and lifts the mattress with one hand to put the corners of the bed-clothes under the mattress.
  • the person must repeat these steps over and over within a little time to make a lot of beds. Therefore a system for helping the person for making the bed has been needed.
  • FIG. 14 shows one of the conventional bed having the helping system disclosed in a document of Japanese patent application (TOKKAI-HEI-3-207308).
  • This bed 1 comprises a base 2, a mattress 3, and an inflatable body 4 provided between the base 2 and the mattress 3.
  • the inflatable body 4 is a square-shaped elastic bag which can be connected with an air supplying means 6 through tubes 5, 7 and a valve 8.
  • These tubes 5, 7 form a passage of compressed air-flow from the air-supplying means 6, while the valve 8 provided between the above tubes 5, 7 is responsible to block or permit the air-flow to the inflatable body 4.
  • the air supplying means 6 is an air-supply tube connected to an air compressor, a gas cylinder or the like for supplying a large amount of compressed air to the inflatable body 4. In the figure, however, only one end of the air-supply tube is shown.

  • valve 8 opening the valve 8 to release the air from the inflatable body 4 to move down the mattress 3, resulting that the corners of the bed-clothes 9 are placed between the mattress 3 and the base 2.
  • the conventional system requires a large amount of compressed air from the air-supplying means 6 connected to the air compressor or the like to fill the inflatable body 4.
  • the hotel requires a large amount of compressed air from the air-supplying means 6 connected to the air compressor or the like to fill the inflatable body 4.
  • An object of the invention is to provide a bed comprising at least one inflatable means having a plurality of inflatable parts and a plurality of non-inflatable parts both provided between a base and a mattress.
  • Each non-inflatable part is localized in alternate inflatable parts so as to communicate with each other to make a loop around an outer peripheral portion of the top face of the base.
  • the inflatable means is connected to an air-supplying means to obtain a supply of compressed air.
  • the inflatable parts has a bulbous shape, while the non-inflatable parts has a tubular shape.
  • the inflatable means is a generally closed circular tube having a plurality of portions as inflatable parts and a plurality of covered surface portions with short sleeves as non-inflatable parts.
  • the inflatable means is a generally O-shaped air bag having selectively sealed areas as non-inflatable parts.
  • the inflatable means are divided into two independent parts, i.e., one part is laid on one side of the top surface of the base, while the other part is laid on the other side of the top surface of the base.
  • each part is independently connected to the air-supplying means.
  • the air-supplying means is a foot pump, but not limited to.

  • FIG. 13 is a view of the bed having the system of FIG. 9, in which the system is in still another operating condition;
  • FIG. 14 is a view of the bed having the conventional system of moving the mattress up and down.
  • FIGS. 1 to 3 shows one of the embodiments in accordance with the present invention.
  • a bed 11 comprises a base 12, a mattress 13 provided on a top face 12A of the base 12, a inflatable means 15 provided between the base 12 and the mattress 13, and an air-supplying tube 18 connected with a part of the inflatable means 15.
  • the inflatable means 15 is made of a plasto-elastic material such as vinyl chloride, synthetic rubber or the like.
  • This means 15 comprises a plurality of bulbous parts 16 having a comparatively thin layer for inflating with a supply of compressed air and a plurality of tubular parts 17 having a comparatively thick layer for maintaining its size against the air flow.
  • each tubular part 17 is alternatively connected with the bulbous parts so as to communicate each other. Therefore the inflatable means 15 is provided as a loop around an outer peripheral portion of the top face 12A of the base 12.
  • the air-supplying tube 18 has a free end which can be adapted to one end of a connector 20 having a non-return valve 19.
  • the compressed air is supplied from a portable foot pump 21 having an outlet tube 22 adaptable to the other end of the connector 20. Therefore the air-supplying tube 18 can be connected with the pump 21 through the connector 20.
  • the globular parts 16 fill out and the mattress 13 is lifted up from the base 12.
  • the globular parts 16 is flattened by a weight of the mattress 13.
  • a process of making a bed using the above system in accordance with the first embodiment of the present invention is as follows (see FIGS. 2 and 3):

  • the inflatable means 33 is a closed circular tube made of a plasto-elastic material such as vinyl chloride, synthetic rubber or the like.
  • the tube 33 is provided as a loop around an outer peripheral portion of the top face 12A of the base 12 and is partially covered with a plurality of short sleeves 34 of a hard material such as a metal, a hard resin or the like. These sleeves 34 are spaced with each other at regular intervals on the tube 33 to make inflatable portions of the tube 33 between the sleeves 34.
  • These inflatable portions can be filled by a supplying compressed air, while sleeve-covered portions are not.
  • the compressed air is supplied from a portable foot pump 21 which is a same one as used in the first embodiment.
  • a process of making a bed using a system in accordance with the second embodiment of the present invention is as follows (see FIGS. 5 and 6):
  • FIGS. 7 and 8 shows a third embodiment in accordance with the present invention, which is the same as one of the first and second embodiments, except that an inflatable means 42 is in the form of a generally "O"-shaped air bag to make a loop around an outer peripheral portion of the top face 12A of the base 12.
  • the inflatable means 33 is made of two fixed plasto-elastic sheets such as vinyl chloride sheets, synthetic rubber sheets or the like and is sealed in selected areas to make a non-inflatable portions 43 at regular interval.
  • the compressed air is supplied from a portable foot pump as in the first embodiment.
  • a process of making a bed using a system in accordance with the third embodiment of the present invention is as follows (see FIGS. 7 and 8);
  • FIGS. 9 to 13 show another embodiment of the present invention.
  • the inflatable means are separated into first and second inflatable systems 52A, 52B.
  • One system is laid on one side of the top surface of the base, while the other system is laid on the other side of thereof.
  • Each system is independently connected to the air-supplying means, so that it is possible to inflate only one system to lift the one side of the mattress (see FIG. 12).
  • the inflatable means 52 having two expanding systems 52A, 52B which are made of a plasto-elastic material such as vinyl chloride, synthetic rubber or the like.
  • Each system comprises a plurality of inflatable parts 53 and a plurality of non-inflatable tubular parts 54.
  • each tubular part 17 is provided between the inflatable parts 53 so as to communicate each other.
  • the systems 52A, 52B are connected with air-supplying tubes 18, respectively.

  • the inflatable parts 53 are flattened by a weight of the mattress 13 and the mattress 13 is laid on the base 12. On the other hand, when the air is supplied from the pump 21, the inflatable parts 53 are filled up and the mattress become separate from the base.
  • a process of making a bed using the above systems is as follows:
  • the beds having inflating means in accordance with the present invention will help the person who makes the bed.
  • the inflating means described in (1) to (4) do not require a large amount of the compressed air because the mattress 13 can be easily lifted up by a part of the inflating means provided around the outer peripheral portion of the top face 12A of the base 12. Therefore there is no need to use a large system such as the air compressor or the like for the supply of the compressed air, and also there is no need to re-furbish the building to provide an air-supplying tube in the wall of each guest room of the hotel.
  • the structure of the inflatable means 33 is more simple than that of the first embodiment because the former is formed by only providing the tube with the sleeves.
  • the inflatable means 42 of the third embodiment of the present invention is only made of two sheets, so that its manufacturing cost is comparatively lower than that of the first and the second embodiments.
  • the flattened inflatable means is so thin that it will never affect comfort of the mattress to sleep on.
  • the inflatable means of the fourth embodiment of the present invention has two independent inflating systems, so that it is possible to fill one system to lift the one side of the mattress.
